Word Process all Assignments For Easier Improvements

I ask all of my students to word process all of their assignments.  I have one simple reason- so they can revise their work more easily. In my class students receive a  plus (+)  for above proficient work, a check mark for proficient work, or comments for less than proficient work.  I tell them they can  redo any less than proficient or even proficient work  to improve it. I will take the higher “grade”.  In one  of my college class the students have six assignments per session; I rate each and give comments to explain how to improve the work.  Most students modify their already word processed work in just a few minutes. Almost everyone gets the higher grade.  If anyone does not show improve, then I have a one-on-one with that person. If they had handwritten their work, they would not willingly make changes.
